is an excellent book by John Medina (isbn 978-0-9797777-4-5). As usual I'm going to quote from a few pages:

Students learn better from words and pictures than from words alone.
Students learn better when corresponding words and pictures are presented simultaneously rather than successively.
Students learn better when corresponding words and pictures are presented near to each other rather than far apart on the page or screen.
Students learn better when extraneous material is excluded rather than included.
Students learn better from animation and narration than from animation and on-screen text.

When the brain is fully working, it uses more energy per unit of tissue than a fully exercising quadricep.

Charles Darwin noted… the brains in wild animals were 15 to 30 percent larger than those of their tame, domestic counterparts.

Studies show that a person who is interrupted takes 50 percent longer to accomplish a task.
Not only that, he or she makes up to 50 percent more errors.
